A novel perylene diimide material (perylene diimide tetracid–dihexadecyldimethylammonium bromide, PDTA–DHAB) with a unique hierarchical structure was designed and prepared by an ionic self-assembly (ISA) method. The self-assembly behavior and aggregated structure of the complex were then studied by a variety of techniques such as UV-Vis absorption spectra, differential scanning calorimetry, and two-dimensional X-ray diffraction. With the presence of a rigid linkage, the complex can self-assemble into highly ordered helical columns which further pack into a monoclinic crystalline lattice with dimensions of a = 4.02 nm, b = 3.40 nm, c = 2.90 nm, α = β = 90°, γ = 92°. During heating, the helical supramolecular structure was destroyed and transformed to a lamellar liquid crystalline phase. Furthermore, the complex solution upon the addition of ATP showed a remarkable absorption and fluorescence intensity decrease compared with other anions. These results will provide insight into the rational design of functional materials with a helical supramolecular structure through the ISA method.

通过离子自组装的二酰亚胺衍生物：螺旋超分子结构和ATP的选择性检测

通过离子自组装（ISA）方法设计并制备了一种新颖的per二酰亚胺材料（im二酰亚胺四环-二十六烷基二甲基溴化铵，PDTA-DHAB）。然后通过多种技术研究复合物的自组装行为和聚集结构，例如紫外可见吸收光谱，差示扫描量热法和二维X射线衍射。在存在刚性键的情况下，复合物可以自组装成高度有序的螺旋柱，这些柱进一步堆积成尺寸为a = 4.02 nm，b = 3.40 nm，c = 2.90 nm，α = β = 90的单斜晶格。°，γ= 92°。在加热期间，螺旋形超分子结构被破坏并转变为层状液晶相。此外，与其他阴离子相比，添加ATP的复合溶液显示出显着的吸收和荧光强度降低。这些结果将通过ISA方法提供具有螺旋超分子结构的功能材料的合理设计的见解。
